1. Initial revision. Created from document 8006H.
2. Updated "Ordering Information" on
3. Updated data sheet template.
4. Removed all references to 8K device.
5. Updated characteristic plots of section “Typical Characteristics”, starting on
6. Added characteristic plots:
7. Updated sections:
8. Updated Figures:
9. Update Tables:
longer offered and there are no separate ordering codes for commercial operation
range, the only available option now is industrial. Also, updated some order codes to
reflect changes in leadframe composition and added VQFN package option.
